目的:探究分析二维超声联合四维超声对不同孕周胎儿畸形的诊断价值。方法:将2015年5月-2016年8月期间的1578例孕妇作为研究对象,根据孕周,分为孕早期、孕中期和孕晚期,首先,均给予二维超声检查,针对高度怀疑畸形孕妇,再予以四维超声检查,最终,以分娩结果为标准,分析二维超声联合四维超声诊断胎儿畸形的价值。结果:1578例孕妇中,娩出1627例胎儿,41例合并畸形(2.51%),共涉及58处畸形部位。同时,孕中期胎儿检出率比孕早期、孕晚期高,组间对比,差异显著,具有统计学意义(P<0.05)。另外,二维超声联合四维超声检出率,明显高于单纯二维超声检出率,差异具有统计学意义(P<0.05)。结论:联合二维超声与四维超声检查,可提高不同孕周胎儿畸形的检出率。
Objective: To investigate the diagnostic value of two-dimensional ultrasound combined with four-dimensional ultrasound in fetal malformations at different gestational weeks. Methods: From May 2015 to August 2016, 1578 pregnant women were divided into the first trimester of pregnancy, the second trimester of pregnancy and the third trimester of pregnancy according to gestational age. First, two-dimensional ultrasonography was given to the patients with high suspicion of malformation , And then four-dimensional ultrasound, and finally, the delivery results as a standard, the value of two-dimensional ultrasound combined four-dimensional ultrasound in the diagnosis of fetal malformations. Results: Among 1578 pregnant women, 1627 fetuses were delivered and 41 cases were associated with deformities (2.51%), involving 58 deformities. At the same time, the detection rate of fetuses in the second trimester was higher than that in the first trimester and the third trimester, and there was significant difference between the two groups (P <0.05). In addition, the two-dimensional ultrasound combined four-dimensional ultrasound detection rate was significantly higher than the simple two-dimensional ultrasound detection rate, the difference was statistically significant (P <0.05). Conclusion: Combined two-dimensional ultrasound and four-dimensional ultrasound can improve the detection rate of fetal malformations at different gestational weeks.
